' To all whom it may] confiera.'

' Can'ren,

' one end of the ings 'l designates Be it knownV thatI, VVILLTAM W. .Moa citizen of t'he` United States, residing at Quitma'n, in the county of' Brooks and State of Georgia, have invented a new and useful Casting-Machine; andl'. do hereby declare the following to be ai full, clear,

and exact' description of the invention, such respondingly toy the first cavity, vin combina` tion with a lever and yoke, for reciprocating the movable mold member within a frame".

v'The invent-ion comprises further featurels and combination of parts, as hereinafter set forth, shown in the drawings andrlaimed. In the drawings:-Figure 1 is a view in side elevation of the improved casting machine constructed in accordance with the in. vention. Fig. 2 is a plan view. Fig. 3 is a sectional view on line 3-3 of Fig. 2. Fig. l is an end view. Fig. 5 is a view in end elevation, opposite to that shownin Fig. 4.

Fig. 6 is a sectional view Von line 6-6 of Fig. 1, showing a turpentine dip barrel rimin section, and the movable mold member in elevation. Referring more particularly to the draw a frame or stand, which comprises the side guide bars 2, which at frame terminate in down; wardly extending portions 3 connected b v a transverse bar or base 4 at. their lower ends. The guide bars 2 at their other ends areeounected by the transverse bar 5. A mold member ,6 which is annular in contour,

is provided. Projecting from the outer circumference of. the mold member 6, and upon each side thereof is a lug 7. Bolts or screws 8 pass through the lugs 7 andy into the guide bars 2, so as to hold the mold member stationary upon the frame or staiulpan'd against the bar 5. The mold member (i 1s provided with an annular mohl'eavlty l0,

which is substantially semi-elliptical in cross section, as a preferable contour. Another member 11 is provided having' a similar cavity 12. The two mold members are provided with-slight recesses adapted to register when the two mold members are brought together, thereby. forming a pouring opening, ,through which the metal, such as lead or other material is poured, so as to reach the cavities inA the Imold members. The moldmember 11 is provided with later ally extending lugs 15 adapted to slide upon. the parallel side bars 2 of the frame.

Each ofthe mold members is provided with a central opening 16. Projecting from the wall of the openingof the mold member 11,4and extending slightly inwardly are lugs 17, to which the ends 18 of thevyoke 19 are held by the Cotter pin 20. .The yoke 19 is in .turnpivoted at 21 by the bolt22 to the \lever 23, which` vin turn is pivoted in the' bracket arms 24,' which form a part of the transverse bar 4;., The pivot of the leverl to the bar 4 is inthe form of a. bolt 25.

When casting the tur'pentine` dlp barrel rims, the mold member 11 is broughtin contact with the mold member 6', after which the lead or other material is poured through the opening between the two mold members, so as to reach the cavity, thereby forming the rim. After the 'material has become thoroughly set-the mold member 11 is revciprocated rearwardly upon the bars 2, by

the manipulation' of the lever 23. lVhen separat-ing the mold members the free end ofthe lever 23 is swung backwardly, until its extremity rests upon the surface on which the casting machine rests. When moving the lever 23 to this position the yoke moves the movable mold member backwarclly, the lugs 15 sliding upon the guide. bars 2. Owing to the f act that the yoke is always pulling downwardly and rearwardly it tends to h squarely in contact with the guide bars,

- which will hold the movable mold member substantially in a vertical position and substantially against oscillation. After the movable mold member has been moved rearwardly, t'tstill remaining in-a vertical position, and it being -found that the casting ld theV lugs 15 firmly and adheres in the cavity of the movable mold member, the yoke 19 may be swung upon its pivot to the lever 23, thereby entirely removing the movable mold member clear ber carried by the forward' portions of said side guide bars, a rnovtble mold member,v

having laterally extending lu 's adapted to slide upon said side guide bar seid mold.'
